In mx2_camera_try_fmt(), when applying i.MX25 restrictions to frame sizes,

Enable the LNA amplifier also for DVB-T (like for DVB-T2 and DVB-C);
this greatly improves reception of weak signals without affecting the reception
of the strong ones.

Experimental data (collected with the mipsel STB) on the weakest frequencies
available in my area:

LNA OFF:

MUX          level   BER     picture

RAI mux 4    72%     32000   corrupted
TIMB 2       75%     14      OK
TVA Vicenza  68%     32000   corrupted
RAI mux 2    78%     14      OK

LNA ON:

MUX          level   BER     picture

RAI mux 4    73%     1500    OK
TIMB 2       76%     0       OK
TVA Vicenza  69%     0       OK
RAI mux 2    79%     0       OK

Moreover, with LNA enabled, the PCTV 290e was able to pick up 2 new frequencies
matching the integrated tuner of my Panasonic G20 TV, which is really good.

If the V4L2_EVENT_SUB_FL_SEND_INITIAL was set, then the application expects
to receive an initial event of the initial value of the control.

However, commit c53c2549 that added the new
v4l2_subscribed_event_ops introduced a regression: while the code still queued
that initial event the __v4l2_event_queue_fh() function was modified to ignore
such requests if sev->elems was 0 (meaning that the event subscription wasn't
finished yet).

And sev->elems was only set to a non-zero value after the add operation
returned.

This patch fixes this by passing the elems value to the add function. Then the
add function can set it before queuing the initial event.
